Monitoring Resources
Viewing Information on Resource Usage
■ When the following features are configured globally or per-VLAN,
resource usage is applied across all port groups or all slots with installed
modules:
• ACLs
• QoS configurations that use the following commands:
– QoS device priority (IP Address) through the CLI using the qos
device-priority command
– QoS application port through the CLI using qos tcp-port or qos
udp-port
– VLAN QoS Policies through the CLI using service-policy
• Management VLAN configuration
• DHCP snooping
• Dynamic ARP protection
• Remote mirroring endpoint configuration
• Mirror policies per VLAN through the CLI using monitor service
• Jumbo IP-MTU
■ When the following features are configured per-port, resource usage is
applied only to the slot or port group on which the feature is configured:
• ACLs or QoS applied per-port or per-user through RADIUS
authentication
• ACLs applied per-port through the CLI using the ip access-group or
ipv6 traffic-filter commands
• QoS policies applied per port through the CLI using the service-policy
command
• Mirror policies applied per-port through the CLI using the monitor all
service and service-policy commands
• ICMP rate-limiting through the CLI using the rate-limit icmp command
• Virus throttling applied to any port (when a high connection-rate
client is being throttled or blocked)
